Each portion H, or that part of the roof of the carriage Which projects over each of the drivers platforms at the two ends of the carriage, has a chimney or discharge-pipe, I, af- Xed to it and extended through it and both above and below it, as shown in Fig. 2. Itis intended that this pipe I shall be separate from and come directly over or in a line With the pipe Z of the stove or heating apparatus, in order that the smoke discharged from the latter may be led off through the said pipe I and be discharged above the roof of the carriage.

As passengers .usually enter and depart through the rearmost doorway of the carriage, the front one may be easily employed foi1 the purpose of receiving the heating apparatus.

By having the pipe I arranged in that part of the roof which projects over the drivers platform, instead of running it up through any part of the remainder of the roof, I avoid the dropping of soot into that part of the carriage in which the passengers are to sit. It will readily -be seen that after the heating apparatus may have been removed from one end to the other of a carriage and the carriage is set in motion more or less soot would be likely to fall or bejarred out of that dischargepipe I Whose lower end may not be in connection with the smoke-pipe of the heating apparatus. My arrangement of the pipe I prevents any soot from falling inside of the carriage.

I claim- 1. The arrangement of a stove or heating apparatus Within the doorway of a carriage, as described.

2. The construction of the heating apparatus with the tongue and groove, or their mechanical equivalents, arranged on opposite sides or edges of it and so as to enter the doorframe and receive the door of the carriage when such heating apparatus is arranged within the doorway of such carriage, as set forth.

3. The arrangement of the auxiliary pipe I relatively to the drivers platform, or in the projecting roof thereof, as explained, when the heating apparatus isarranged in the doorway, as set forth.
